Ulendo wokhotakhota wa circuit breaker

Chiyambi cha mayendedwe apaulendo

Lingaliro la curve paulendo lidachokera kudziko la IEC ndipo limagwiritsidwa ntchito kugawa ma micro-circuit breakers (B, C, D, K ndi Z) kuchokera ku miyezo ya IEC.Muyezowu umatanthauzira malire otsika ndi apamwamba pamaulendo, koma opanga ali ndi kuthekera kozindikira zomwe zili mkati mwazigawozi zomwe zingapangitse kuti malonda awo aduke.Zithunzi zaulendo zikuwonetsa madera olekerera komwe wopanga angakhazikitse malo oyendera ophwanya dera.

Ulendo wokhotakhota wa circuit breaker

Makhalidwe ndi kagwiritsidwe kapindika kalikonse, kuyambira kovutirapo kwambiri mpaka kocheperako, ndi:

Z: Ulendo wa 2 mpaka 3 nthawi zovoteledwa pano, zoyenera kugwiritsa ntchito zovuta kwambiri monga zida za semiconductor

B: Ulendo pa 3 mpaka 5 nthawi zovotera panopa

C: Kuyenda maulendo 5 mpaka 10 omwe adavotera panopa, oyenera pakalipano

K: Ulendo wa 10 mpaka 14 nthawi zovoteledwa panopa, zoyenera katundu ndi mkulu inrush panopa, makamaka ntchito motors ndi thiransifoma

D: Kuyenda maulendo 10 mpaka 20 omwe adavotera panopa, oyenera poyambira kwambiri

Kuwunikanso tchati cha "Kuyerekeza kwa ma curve onse a IEC Trip", mutha kuwona kuti mafunde apamwamba amayambitsa maulendo othamanga.

Kukhoza kulimbana ndi mphamvu zamakono ndizofunikira kwambiri pakusankha ma curve aulendo.Katundu wina, makamaka ma motors ndi ma transformer, amakumana ndi kusintha kwakanthawi kwakanthawi, komwe kumadziwika kuti impulse current, pomwe zolumikizira zatsekedwa.Zipangizo zoteteza mwachangu, monga ma curve a b-trip, zitha kuzindikira kuti kuchulukana kumeneku kwalephera ndikuyatsa dera.Kwa mitundu iyi ya katundu, ma curve okhala ndi maginito okwera kwambiri (D kapena K) amatha "kudutsa" pakasefukira komweko, kuteteza dera kuulendo wabodza.
